Ten rugby balls are randomly selected from the production line to see if their shape is correct. Over time, the company has foun
zaharov [31]

Answer:

Step-by-step explanation:

The question is incomplete. The complete question is:

Ten rugby balls are randomly selected from the production line to see if their shape is correct. Over time, the company has found that 89.4% of all their rugby balls have the correct shape. If exactly 6 of the 10 have the right shape, should the company stop the production line?

1)Yes as the probability of six having the correct shape is not unusual

2)NO. as the probability of six having the correct shape is unusual

3)Yes as the probability of six having the correct shape is unusual

4) No. as the probability of six having the correct shape is not unusual

Solution:

If exactly 6 of the 10 have the right shape, it means that the probability of success for the sample is

6/10 = 0.6

Expressing the probability in terms if percentage, it becomes

0.6 × 100 = 60%

Over time, the company has found that 89.4% of all their rugby balls have the correct shape. It means that the probability of success for the population is 89.4%

Comparing both probabilities, the probability of only 6 having the right shape is unusual. Therefore, the correct option is

3)Yes as the probability of six having the correct shape is unusual

On the Venn diagram, which would be classified as an IRRATIONAL number?
AnnyKZ [126]

Answer:

The correct answer is B. 2π

Step-by-step explanation:

A rational number is one that can be represented using a fraction and an irrational number cannot be represented using a fraction.

-√4 = -2, which is a rational number

2π is not a rational number (we cannot express pi as a fraction exactly even though there are some close approximations)

2.2121... is also a rational number because it can be expressed as a fraction (21/99, or 7/33 simplified)

√225 is 15, which is a rational number

Therefore, the only irrational option is option B. 2π, which is your answer.

Hope this helps!
